Train class control unit VCU-M, train network control system and operation method of VCU-M

Abstract

The invention discloses a train class control unit VCU-M, a train network control system and an operation method of the VCU-M. The VCU-M includes a first ETBN board card and a controller, wherein thefirst ETBN board card is connected with the controller and second ETBN board cards arranged in other trains except a train where the VCU-M is located, and used for marshalling an Ethernet, obtaining topology information of the second ETBN board cards and sending a networking completion signal to the controller; and the controller is used for receiving the networking completion signal, obtaining the topology information of a to-be-controlled device from the first ETBN board card, generating a control signal according to the topological information of the to-be-controlled device, and sending thecontrol signal to the to-be-controlled device. According to the train class control unit VCU-M, the train network control system and the operation method of the VCU-M, the ability of adaptive marshalling Ethernet of the trains can be improved.

Description

technical field [0001] The present application relates to the field of train network technology, and in particular to a train-level control unit VCU-M, a train network control system and an operation method of the VCU-M. Background technique [0002] This section is intended to provide a background or context to embodiments of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] With the rapid development of train network technology, the application of Ethernet technology to train network has gradually become a development trend. In order to respond to the needs of train operation, the current train will adjust the length of the train according to the passenger load, so as to reduce the energy consumption of the train and improve the operating efficiency. When the length of the train is adjusted, the Ethernet network formed by the terminal equipment of each train is bound to be re-netw...

AI Technical Summary

Problems solved by technology

When the length of the train is adjusted, the Ethernet network formed by the terminal equipment of each train must be re-networked, which puts forward a new challenge to the ability of the adaptive marshalling Ethernet network of the network control system installed on the current train. High requirements, and the current train network control system still has a certain gap from the above requirements
